Hygienic CIP self-priming pump, return pump working principle and application field

The sanitary CIP self-priming pump is specially designed to handle the suction of materials with a liquid level below the pump inlet and the transport of fluid materials containing a portion of the gas. The self-priming pump casing, pump cover and impeller are all made of high quality stainless steel 304 or 316L manufacture. The motor is equipped with a stainless steel cover. The inner surface mirror polishing roughness Ra0.28um. The outer cover is brushed matt finish. Fully compliant with GMP requirements.

working principle

The sanitary CIP self-priming pump is designed to absorb liquids mixed with air or foam, and can even be pumped by itself when there is intermittent air. The pump has excellent performance, reasonable structure, small volume and reliable use.

Structural features

The sanitary CIP self-priming pump is a single-stage self-priming positive displacement pump, which is composed of a pump cover, an impeller, a pump body and a motor. The impeller is star-shaped, and the pump cover pump body constitutes the inner cavity of the pump. When the impeller rotates in the inner cavity of the pump, the volume composed of the impeller spoke and the inner cavity gradually increases from the suction port to the discharge port. The capacity is gradually reduced. Therefore, the liquid contained in the impeller spoke can be made into a reciprocating action of suction and discharge to form a certain self-suction capability.

Application field

Hygienic self-priming pumps are mainly used in the pharmaceutical, alcohol, food, chemical, beverage and other industries that require self-priming and liquid transport containing a portion of the gas. Especially for the backhaul pump in the CIP in-situ cleaning system.
